Poços de Caldas

Where did Poços de Caldas begin?

Poços de Caldas is a municipality located in the south of Minas Gerais state, Brazil, within the microregion of the same name. Situated on a high plateau at an elevation of 1,186 meters on the boundary of the state of São Paulo, the municipality covers a total area of 547 square kilometers.

The history of the area marked a major turning point when the original inhabitants, the Cataguases Indians, were expelled from their lands by the Bandeiras Unidas Paulistas during their quest for gold. Originally established as the Freguesia de Nossa Senhora da Saúde das Águas de Caldas, the settlement was founded in 1872. Following its founding, the locality transitioned rapidly through administrative milestones, becoming a district in 1874 and attaining city status in 1875. The discovery of its thermal springs transformed the destination into a prominent spa town, drawing many important visitors seeking water cures and anchoring its long-term identity as a hydro-mineral center.

Where Is Poços de Caldas Located?

Poços de Caldas is a municipality situated in the southern part of the Minas Gerais state, Brazil, within the microregion of the same name. The city recorded an estimated population of 163,742 inhabitants during the 2022 Census, and administrative registers report a population of 172,339.

What Led to the Historical Turning Point of Its Foundation?

The territory was originally inhabited by the Cataguases Indians, who were subsequently expelled from their ancestral lands by the Bandeiras Unidas Paulistas during their expeditions in search of gold. Following this displacement, the location underwent a major historical turning point when it was officially founded in 1872 under the initial designation Freguesia de Nossa Senhora da Saúde das Águas de Caldas, translating to the Parish of Our Lady of Health of Caldas Waters.

The settlement quickly transitioned through administrative milestones, becoming a district in 1874 and attaining city status the following year in 1875. The discovery of local hot springs served as a catalyst for widespread fame, drawing numerous prominent visitors to the spa in pursuit of the therapeutic cures provided by the water. This hydro-mineral abundance inspired the adoption of a name derived from Caldas da Rainha, a recognized spa town located in central Portugal.

How Did the Geography Shape Its Development?

The municipality lies directly on the boundary of the state of São Paulo at an elevation of 1,186 meters, acting as the primary socio-economic nucleus of its region. Spanning an area of 547 square kilometers—which includes 85 square kilometers of urban territory and 459 square kilometers of rural land—the physical expanse sits upon a high plateau shaped by mountains, fields, and valleys. While the surrounding elevated areas possess a volcanic origin, the distinct caldera setting was actually formed through the structural collapse of a central portion of terrain rather than direct volcanic activity.

The city expanded its economic foundation far beyond its early spa reputation. It developed substantial mining and industrial operations, including Brazil's first uranium-ore concentration plant, major bauxite extractions managed by Alcoa, and traditional manufacturing of internationally renowned glass and soap products.
